Explanation / Answer

Given an unsorted list of items,

Sequential Search: It is nothing but the linear search, it visits each and every element in the list and finds the element, If it matches returns true.

For Binary search, Interpolation search they need the sorted listed of items to proceed further.

So only sequential search is guaranteed to return the index of a given search item in an unsorted list of items.
